Abstract
The utility model relates to a horizontal high temperature carbonization furnace, which is composed of a furnace door (1), a furnace body, electric heating elements (6), (14) and a material setting mechanism. The utility model is characterized in that the horizontal high temperature carbonization furnace is additionally provided with a nitrogen circulation device outside and inside the furnace and a material cart track (15), a furnace inner wall (5) is composed of tubular refractory material arranged and combined together. An electric heating wire (20) is wound on a high aluminium tube (19), and the electric heating wire is exposed in a hearth. The furnace temperature of the carbonization furnace can reach 950 DEG C, and the carbonization furnace has temperature rise for 4.5 hours. Pyrolysis gas is obviously divided into three stages of 450-550DEG. C, 650-700DEG. C and 750-900DEG. C, which indicates that the temperature of the surface of the material and the center of the material is uniform. In addition, the carbonization furnace has simple operation.
Description
The utility model relates to a kind of horizontal retort that is used for the charcoal fiber production.
The device of industrial existing production asphalt carbon fibre is divided into vertical and horizontal two kinds.Vertical high temperature carbonization stove as Japanese CHUGAIRO is made up of body of heater and stone or metal plate for standing a stove on as a precaution against fire, around the inboard wall of furnace body is that refractory materials is made, electrical heating element is shelved therebetween, material places and is put in the metal cylinder on the charing stone or metal plate for standing a stove on as a precaution against fire, is covered in the stove by body of heater, and this structure heating is slow, it is also slow to dispel the heat, thermal source surface temperature and technological temperature gradient are up to more than 100 ℃, thereby the electrical heating element easy burn-out, and stove production efficiency is low.As the Shanxi coalification its electrical heating element of horizontal-type high temperature charring furnace also be shelve be embedded in by refractory materials make around in the furnace wall, material places in the metal box courage, this case courage horizontal suspended is in burner hearth, this structure not only has the shortcoming of above-mentioned vertical structure, and in the heating and cooling process, also need the case courage is put into, extract out, cooling not only influences equipment life suddenly, operation is also inconvenient, only is suitable for small-sized.
The purpose of this utility model is to develop in a kind of stove uniformity of temperature profile, intensification and lowers the temperature rapidly, easy and simple to handle, and can be used for industrial horizontal-type high temperature charring furnace.
Horizontal-type high temperature charring furnace of the present utility model is made up of stove outer covering, stove inwall, insulation, electrical heating element, fire door and material placing machine structure, it is characterized in that having set up the inside and outside nitrogen circulation refrigerating unit of stove.
Embodiment accompanying drawings of the present utility model is as follows.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure in the stove synoptic diagram.
As shown in the figure, 1 is fire door, and 2 are the fire door insulation, and 3 is stove outer covering, 4 is furnace insulation, and 5 is the stove inwall, and 6 is the upper strata electrical heating element, and 7 is gas exhaust duct, 8 is blow-off valve, and 9 is water cooler, and 10 is induced draft fan, and 11 is the circulating flow rate variable valve, 12 is nitrogen adjustment valve, and 13 is nitrogen pipeline, and 14 is lower floor's electrical heating element, 15 is the truck track, and 16 is material frame car, and 17 is the tubular fire material, 18 is slide block at the bottom of the frame car, and 19 is high aluminum pipe, and 20 is nichrome wire.
As shown in the figure, wrap up by shell 3, furnace insulation 4, stove inwall 5 around the stove; Frame has tubular fire material 17 around the inwall, and the electrical heating element 6 of levels and 14 is made of high aluminum pipe 19 and nichrome wire 20, and nichrome wire 20 is wrapped on the high aluminum pipe 19; Slide block 18 at the bottom of the frame car is arranged between material frame car 16 and the truck track 15, and truck 16 can slide between the truck track; Nitrogen inlet tube 13 is below electrical heating element 14, and the nitrogen fairlead is above electrical heating element 6; Induced draft fan 10 sucks N through gas exhaust duct 7, water cooler 9
2, through circulating flow rate variable valve 11 again N
2Be blown in the stove, make stove at N
2Protection circulation down cools.
The technological operation step is as follows: open fire door 1, along truck track 15 material frame car 16 is pushed in the stove, add fire door insulation 2, close fire door 1, open nitrogen adjustment valve 12, nitrogen feeds along pipeline 13, the energising heating, entered burner hearth after 14 heating of lower floor's electrical heating element, with material protection heating charing, waste gas is discharged through gas exhaust duct 7 and blow-off valve 8; When body of heater cooling cooling, close blow-off valve 8 earlier, open induced draft fan 10 and circulating flow rate variable valve 11, through pipeline 13 → burner hearth → pipeline 7 → water cooler 9 → induced draft fan 10, circulation cools.
Test shows that advantage of the present utility model is as follows:
1, Temperature Distribution meets the charring process rule
The technological temperature of retort is 950 ℃, 4.5 hours heating-up times, aobvious branch when cracked gas discharges Be three phases: 450-550 ℃, 650-700 ℃, 750-900 ℃, this shows material top layer and center Temperature is consistent.
The charring furnace of prior art inflated with nitrogen after vacuum is evacuated to 700mmHg, 5.5 hours heating-up times; Cracked gas discharges follows the technology whole process, promptly 450-1000 ℃, shows that thus there is the big temperature difference at material top layer and center.
2. easy and simple to handle.
